The container 1 is preferably partially or wholly transparent or translucent, whereby the remaining amount of the contents can be confirmed from the outside. The material of the container 1 is not particularly limited, but can be formed of, for example, an elastically deformable synthetic resin material such as polyethylene terephthalate, polyethylene, or polypropylene. When the container 1 is formed of a synthetic resin material, it can be manufactured by a known blow molding, for example, injection blow molding, that is, after the preform is manufactured by an injection molding method, the preform is formed into the outer shape of the container 1. It is possible to use a molding method in which the preform is inflated by a stretch blow molding method by inserting it into a mold having a molding surface corresponding to the above. The thickness of the container 1 is not particularly limited, but may be, for example, 0.2 mm or more and 2 mm or less.

The container 1 extends upward to the center of the bottom portion 10, the hollow body portion 11 rising from the outer peripheral edge of the bottom portion 10, the shoulder portion 12 connected to the upper end of the body portion 11 so as to face the body portion 11, and the center of the shoulder portion 12. The tubular mouth portion 13 and the like are included. The space surrounded by the body portion 11 on the bottom portion 10 is the storage space for the contents.

Explanation of the Mouth As shown in FIGS. 4 to 10, the mouth 13 of the container 1 has a cylindrical shape, although it is not particularly limited, and the cross-sectional view of the inner wall surface and the outer wall surface is circular. In the present disclosure, the cross-sectional view shape is a shape of a cross section along the horizontal direction. Further, the vertical cross-sectional view shape is a shape of a cross section along the vertical direction.

The upper and lower ends of the mouth portion 13 are open, the upper end opening 130 is the pouring port for the contents, and the lower end opening is the communication port with the shoulder portion 12 and the body portion 11. A cap 2 capable of closing the opening 130 at the upper end is detachably attached to the mouth portion 13. A male screw (not shown) is provided on the upper portion of the outer wall surface of the mouth portion 13. This male screw is screwed with the female screw (not shown) of the cap 2 (shown in FIGS. 1 and 2) so that the cap 2 attached to the mouth portion 13 cannot be easily removed from the mouth portion 13. It can be connected. The means for attaching the cap 2 to the mouth portion 13 and connecting the two is not particularly limited, and various other known means can be used. Further, the mouth portion 13 may not be provided with a connecting means such as a male screw, and the mouth portion 13 may be simply fitted in the cap 2.

As shown in FIGS. 1 and 11, the cap 2 attached to the mouth portion 13 includes a top surface portion 20 having a circular shape in a plan view and a peripheral surface portion 21 hanging from the outer peripheral edge of the upper surface portion. The cap 2 is not particularly limited, but is formed of an elastically deformable synthetic resin material. The peripheral surface portion 21 can insert the mouth portion 13 of the container 1 inside, and the lower portion of the inner wall surface of the peripheral surface portion 21 has a male screw (not shown) provided on the outer wall surface of the mouth portion 13. A female screw (not shown) to be screwed is provided. A protrusion 22 protruding downward is provided on the lower surface of the top surface portion 20.

Returning to the description of the mouth portion 13 of the container 1, as shown in FIGS. 4 to 10, a pair of constricted portions 131 are provided at the lower portion of the outer wall surface of the mouth portion 13. The pair of constricted portions 131 is formed by denting a part of the mouth portion 13 inward in a concave shape. The pair of constricted portions 131 are arranged so as to face each other. The internal space of the mouth portion 13 is narrowed by the pair of constricted portions 131, and a rectangular void 132 in a plan view is formed between the pair of constricted portions 131.

Here, when the container with a cover is used for the drug volatilizer, the liquid absorbing core material 3 is inserted into the container 1 from the gap 132. As shown in FIG. 11, the liquid absorbing core material 3 inserted into the container 1 is pulled up so that a part on the upper end side protrudes upward from the container 1 to remove the contents (liquid chemicals) in the container 1. It is sucked up by capillarity and volatilized in the external space. At this time, since the cross-sectional view of the void 132 is smaller than the cross-sectional view of the liquid-absorbing core material 3, the liquid-absorbing core material 3 is pressed by the pair of constricted portions 131 while the liquid-absorbing core material 3 is paired. It is sandwiched by the constricted portion 131. As a result, the liquid absorbing core material 3 is held in a pulled-up state.

The liquid absorbing core material 3 is not particularly limited, but exhibits an elongated strip shape. The material of the liquid absorbing core material 3 is not particularly limited as long as the liquid medicine in the container 1 can be sucked up by the capillary phenomenon and the sucked up liquid medicine can be volatilized in the external space. For example, various fibrous materials such as nylon, rayon, polyester (for example, polyethylene terephthalate), polypropylene, polyethylene, and pulp can be mentioned as the material of the liquid absorbing core material 3, and these materials may be used alone. , Or a combination of two or more. The liquid absorbing core material 3 is not particularly limited, but a non-woven fabric produced by an airlaid method, a needle punching method, a spunbond method, a spunlace method or the like is suitable.

The liquid absorbing core material 3 is not particularly limited, but as shown in FIG. 11, a part in the length direction is wound around the pulling member 4 to be attached to the pulling member 4, and the container is attached to the pulling member 4 in a state of being attached to the container. It is inserted in 1. The other portion of the liquid absorbing core material 3 in the length direction hangs down from the pulling member 4, and the lower end thereof is in contact with the bottom portion 10 of the container 1.

The pulling member 4 is inserted into the container 1 from the gap 132 of the mouth portion 13 of the container 1, and is attached to the mouth portion 13 so as to be slidable in the vertical direction. By sliding the pulling member 4 upward, the liquid absorbing core material 3 is pulled up from the inside of the container 1. The pulling member 4 is not particularly limited, but is formed of an elastically deformable synthetic resin material. The pulling member 4 is rotatably and detachably connected to the top surface portion 20 of the cap 2 and is held by the cap 2 in a suspended state.

As shown in FIG. 11, the pulling member 4 is a frame member having a rectangular shape in front view and having an upper side portion 40 and a pair of side side portions 41. The pair of side edges 41 extend downward from both ends of the upper edge 40. Below the upper side portion 40, a pair of upper and lower beam portions (not shown) extending in parallel with the upper side portion 40 are provided between the pair of side side portions 41, and the liquid absorbing core material 3 is provided on the upper and lower pair of beam portions. Wrapped around.

The length of the upper side portion 40, that is, the length between the pair of side side portions 41 is slightly smaller than the inner diameter of the mouth portion 13 of the container 1, whereby the pulling member 4 is placed in the container from the gap 132 of the mouth portion 13. It is inserted in 1. The upper side portion 40 is provided with an annular fitting portion 42 in which a protrusion 22 protruding downward from the top surface portion 20 of the cap 2 is rotatably fitted, whereby the pulling member 4 is rotatable and detachable with respect to the cap 2. It is possible.

At the lower ends of the pair of side sides 41, an engaging claw 43 protruding outward is provided. Each engaging claw 43 engages with the corresponding raised portion 123 of the shoulder portion 12 of the container 1 described later when the pulling member 4 is slid upward, and the pulling member 4 is further slid upward. Regulate what you do.

Explanation of the shoulder portion As shown in FIGS. 4 to 10, the shoulder portion 12 of the container 1 has a plan-view shape one size larger than the mouth portion 13 and one size smaller than the body portion 11, and is between the shoulder portion 11 and the body portion 11. Has a step in. The shoulder portion 12 has a polygonal shape (12-sided shape in the present embodiment), although is not particularly limited, so as to extend downward from the upper surface portion 120 connected to the lower end of the mouth portion 13 and the outer peripheral edge of the upper surface portion 120. It includes a continuous side surface portion 121 and a horizontal and flat lower surface portion 122 that connects the lower end of the side surface portion 121 and the upper end of the body portion 11.

The upper surface portion 120 is not particularly limited, but is inclined low in the direction from the mouth portion 13 to the side surface portion 121. The upper surface portion 130 is provided with a plurality of raised portions 123 around the mouth portion 13 at intervals in the circumferential direction. The plurality of raised portions 123 are preferably arranged at equal intervals, and in the present embodiment, the two raised portions 123 are arranged at intervals of 180 degrees. The raised portion 123 is formed by raising a part of the upper surface portion 121 in a convex shape, and is located one step higher than the other portions of the upper surface portion 121. The raised portion 123 has a substantially rectangular shape in a plan view in which the length (depth) along the circumferential direction of the mouth portion 13 is larger than the length (horizontal width) in the direction in which the upper surface portion is separated from the mouth portion 13 in the radial direction. It is horizontally and flatly connected to the lower end of the mouth portion 13. As shown in FIG. 11, the raised portion 123 hooks the corresponding engaging claw 43 of the pulling member 4 on the upper surface portion when the pulling member 4 inserted into the container 1 is slid upward. It can be stopped and prevents the pulling member 4 from coming out of the container 1.

When the pulling member 4 inserted in the container 1 is slid upward without providing the plurality of raised portions 123 on the upper surface portion 120, the plurality of engaging claws 43 of the pulling member 4 are engaged with the upper surface portion 120. You may combine them. However, in this case, since the upper surface portion 120 is inclined lower toward the side surface portion 121, the plurality of engaging claws 43 of the pulling member 4 are likely to be displaced inward when engaged with the upper surface portion 120. , The engagement with the upper surface portion 120 is likely to be disengaged. On the other hand, by providing the raised portion 123 including the horizontal and flat upper surface portion on the upper surface portion 120, the plurality of engaging claws 43 of the pulling member 4 are displaced inward when engaged with the corresponding raised portion 123. It becomes difficult to do so, and the engagement with the upper surface portion 120 can be strengthened.

The side surface portion 121 is not particularly limited, but as shown in FIGS. 4 to 10, the side surface portion 121 is inclined in a hem-spreading shape so that the lower end connected to the lower surface portion 122 is located on the outer side of the upper end connected to the upper surface portion 120. .. A plurality of overhanging portions 124 are provided at the corners of the side surface portion 121 and the upper surface portion 120 at intervals in the circumferential direction. The plurality of overhanging portions 124 are preferably arranged at equal intervals, and in the present embodiment, the four overhanging portions 124 are arranged at intervals of 90 degrees. The overhanging portion 124 is formed by projecting a part of the upper surface portion 120 in a convex shape and a part of the side surface portion 121 in a convex shape to the outside, and horizontally and flatly outward from the upper surface portion 120. A horizontal portion having a rectangular shape in a plan view protruding from the horizontal portion and a vertical portion having a rectangular shape in a front view hanging from the tip of the horizontal portion are included, and the side view exhibits a substantially right-angled triangular shape.

The upper surface portion 120 and the side surface portion 121 of the shoulder portion 12 have obtuse angles. Therefore, if an impact is applied to the corners of the upper surface portion 120 and the side surface portion 121 by dropping the container 1 onto the floor or the like, the corners may be easily dented and the container 1 may be damaged. On the other hand, by providing a plurality of overhanging portions 124 at the corners of the upper surface portion 120 and the side surface portion 121, the corners of the overhanging portion 124 are at right angles and are strong against impact, and the container 1 is dropped on the floor or the like. However, when an impact is applied to the plurality of overhanging portions 124, the overhanging portion 124 is less likely to be dented, and the corners of the upper surface portion 120 and the side surface portion 121 are not dented, so that damage to the container 1 can be suppressed. ..

A plurality of recesses 125 are provided at the lower ends of the side surface portions 121 at intervals in the circumferential direction. The plurality of recesses 125 are preferably arranged at equal intervals, and in the present embodiment, the four recesses 125 are arranged at 90 degree intervals and are located directly below the four overhanging portions 124. The recess 125 is formed by denting a part of the side surface portion 121 inward in a concave shape. The recess 125 is not particularly limited, but exhibits an elongated shape (horizontally long shape) extending long in the circumferential direction.

The plurality of recesses 125 can accommodate a plurality of (four in this embodiment) convex portions 52 (shown in FIGS. 12 and 13) provided in the cover 5 described later. As shown in FIGS. 16 and 17, the details will be described later, but the cover 5 attached to the container 1 cannot be easily removed from the container 1 by hooking the convex portion 52 that has entered the concave portion 125 and stopping the convex portion 52. Both can be connected.

As shown in FIGS. 1, 9, and 10, the plurality of recesses 125 have a vertical width (up and down) according to the height position and the vertical width (length in the vertical direction) of the convex portion 52 of the cover 5 that enters each of the recesses 125. The length in the direction, specifically, the length extending upward from the upper surface of the lower surface portion 122) is different. In the present embodiment, of the four recesses 125, the pair of recesses 125 (hereinafter, also referred to as “first recess 125A”) located on the front side and the back side of the container 1 are on the left and right side surface sides of the container 1. The vertical width is larger than the pair of recesses 125 (hereinafter, also referred to as "second recess 125B") located in.

The lower surface portion 122 extends horizontally and flatly outward from the lower end of the side surface portion 121 and is connected to the upper end of the body portion 11. As shown in FIGS. 2 and 3, the lower end surface portion 122 abuts on the lower end of the peripheral surface portion 51 of the cover 5 when the cover 5 is attached to the container 1.

Description of the Body The body 11 of the container 1 includes facing front portions 110 and back portions 111, and facing left and right side surface portions 112 and 113, as shown in FIGS. 4 to 10. Further, the body portion 11 is a back surface located between the front surface portion 110 and the pair of front side connecting portions 114 located between the left and right side surface portions 112 and 113, and the back surface portion 111 and the left and right side surface portions 112 and 113. Further includes a pair of side connecting portions 115. The body portion 11 has the front portion 110, the connecting portion 114, the side surface portion 112, the connecting portion 115, the back portion 111, the connecting portion 115, the side surface portion 113, and the connecting portion 114 in the circumferential direction between the bottom portion 10 and the shoulder portion 12. It is formed by connecting it in a tubular shape.

The body portion 11 preferably has a flat shape in which the lateral width (length in the front-rear direction) is shorter than the lateral width (length in the left-right direction) in the front-back view. As a result, the container 1 can be easily gripped, the design of the container 1 can be improved, and a large display area of the exterior film 6 (shown in FIG. 18) can be secured on the front portion 110 and the back portion 111. be. Further, the height (length in the vertical direction) of the body portion 11 is preferably shorter than the horizontal width in the front-back view. As a result, since the height of the container 1 is lowered, it is possible to suppress the dent of the container 1 when a negative pressure is generated inside the container as compared with the case where the height of the container 1 is high. The height of the body portion 11 is preferably within twice the width of the front-back view.

The front surface portion 110 is not particularly limited, but is composed of a plurality of panel portions 1100 arranged side by side in the left-right direction. In the present embodiment, the front portion 110 is configured by the three panel portions 1100. The panel portion 1100 is not particularly limited, but exhibits a rectangular shape in the front view that is long in the vertical direction. The plurality of panel portions 1100 are connected so that the boundary with the adjacent panel portions 1100 is angular. That is, in the cross-sectional view, the front portion 110 is connected in a V shape so that the adjacent panel portions 1100 form an obtuse angle, and exhibits a shape that is bent into a polygon as a whole. As a result, the front portion 110 has a ridge line (corner) extending in the vertical direction at the boundary between the panel portions 1100 adjacent to each other in the left-right direction. The obtuse angle created by the adjacent panel portions 1100 in the cross-sectional view of the front portion 110 does not necessarily have to be sharp, and the tip may be rounded. In this way, the front portion 110 is formed by connecting a plurality of panel portions 1100 extending in the vertical direction so as to have an angular boundary between the panel portions adjacent to each other in the left-right direction and the panel portions 1100, so that the front portion 110 is convex outward. It is said to be a bulging part that swells. The panel portion 110 extends vertically straight from the shoulder portion 12 toward the bottom portion 10 in a vertical cross-sectional view from the side surface side, and the panel portion 110 is formed on a flat surface. In the vertical cross-sectional view, the panel portion 110 may be curved outward from the shoulder portion 12 toward the bottom portion 10, and the panel portion 110 may be formed on a convex curved surface. ..

The front portion 110 is provided with a concave groove 1101 extending in the vertical direction along the boundary between adjacent panel portions 1100. The groove 1101 is formed by denting a part of the body portion 11 inward in a concave shape. The cross-sectional view shape of the groove 1101 is not particularly limited, and may have a V-shaped or U-shaped bottom with an angular bottom, but preferably a U-shaped or semicircular bottom with a rounded bottom. It has a tinged shape.

In order to manufacture the container 1 by injection blow molding, first, the preform is manufactured by injection molding. At this time, when the preform is molded by laminating a plurality of resin layers, the cross-sectional view shape of the groove 1101 is formed. If the bottom is angular, such as a V-shape, a gap is likely to be formed between the resin layers laminated at the portion of the groove 1101. Therefore, when the preform is taken out from the mold, a part of the resin layer may be peeled off. However, if the cross-sectional view of the groove 1101 is U-shaped or the like, the bottom is rounded. Since it is difficult for a gap to be formed between the resin layers laminated in the portion of the groove 1101, it is possible to prevent a part of the resin layer from peeling off when the preform is taken out from the mold.

Since the panel portion 1100 is sandwiched by the two grooves 1101 due to the presence of the plurality of grooves 1101 at intervals in the left-right direction on the front portion 110, the panel portion 1100 becomes a columnar rib and its mechanical strength is increased. Be done. In the body portion 11, the front portion 110 is a portion having a particularly large surface area, and the panel portion 1100 has a low mechanical strength because it bulges outward in a convex shape, and when negative pressure is generated in the container 1, the panel is formed. Part 1100 is very easy to dent. Therefore, by providing the groove 1101 at the boundary (corner) of the adjacent panel portions 1100, which is a portion having high mechanical strength in the front portion 110, the mechanical strength of the front portion 110 can be increased as a whole. The panel portions 1100 at both ends in the left-right direction are provided with grooves 1101 extending in the vertical direction along the boundary (corner) with the adjacent connecting portions 114, and the panel portions 1100 also have two grooves. It is sandwiched by the grooves 1101 to increase its mechanical strength.

The depth of the groove 1101 is not particularly limited, but if the depth is large, the mechanical strength of the panel portion 1100 can be satisfactorily improved, but if the depth is too large, molding of the container 1 becomes difficult, which is preferable. It is 1 mm or more and 10 mm or less, and more preferably 2 mm or more and 4 mm or less.

The length of the groove 1101 (length in the vertical direction) is not particularly limited, but if the length is large, the mechanical strength of the panel portion 1100 can be improved as a whole, but if the length is too large, the appearance is impaired. Therefore, it is preferably 1/5 * or more and 9/10 or less of the height (length in the vertical direction) of the body portion 11, and more preferably 3/5 or more and 4/5 or less.

The width (length in the left-right direction) of the groove 1101 is not particularly limited, but if the length is too large, the width of the panel portion is reduced and the pressure absorption effect is reduced, and if the length is too small, the mechanical strength is reduced. Since it is insufficient, it is preferably 1 mm or more and 15 mm or less, and more preferably 3 mm or more and 10 mm or less.

The distance between the adjacent grooves 1101, that is, the width of the panel portion 1100 is not particularly limited, but if the distance is small, the mechanical strength of the panel portion 1100 can be satisfactorily improved, but if the distance is too small, the pressure absorption effect is obtained. Is preferably 5 mm or more and 40 mm or less, and more preferably 10 mm or more and 25 mm or less.

The groove 1101 preferably gradually widens from both ends in the vertical direction toward the center. In the panel portion 1100, the central portion in the vertical direction farthest from the corners of the shoulder portion 12 and the bottom portion 10 has particularly low mechanical strength and tends to be dented. By increasing the width of the center of the groove 1101 in the vertical direction, the mechanical strength of the central portion of the panel portion 1100 in the vertical direction can be effectively increased, and dents can be prevented. The groove 1101 does not necessarily have to gradually widen from both ends in the vertical direction toward the center, and the groove 1101 may have a uniform width over the entire length in the vertical direction.

The back surface portion 111 is not particularly limited, but the left and right side edges are curved outward in the left-right direction in a convex shape. Further, the back surface portion 111 is not particularly limited, but is curved inward from the shoulder portion 12 toward the bottom portion 10 in a vertical cross-sectional view from the side surface side, and the back surface portion 11 is formed into a concave curved surface. On the other hand, in the cross-sectional view, it is curved outward from one connecting portion 115 toward the other connecting portion 115. Since the back surface portion 111 is formed on a concave curved surface, its mechanical strength is enhanced, and the structure is such that it is difficult to dent.

As shown in FIG. 10, the rear end portion 111 has the lower end portion 1110 most protruding outward in a vertical cross-sectional view from the side surface side. That is, in the back surface portion 111 which is concave and curved inward from the shoulder portion 12 toward the bottom portion 10 in the vertical cross-sectional view, the lower end portion 1110 is located outside the upper end portion 1111. As a result, as shown in FIG. 19, when the other containers 1 are arranged directly opposite the back surface portion 111, the lower end portion 1110 abuts on the other container 1, whereas the upper end portion 1111 is the other. A gap is created between the container 1 and the other container 1 without contacting the container 1.

The lower end portion 1110 means a part including the lower end or a part slightly above the lower end, and the back surface portion 111 is located outside the lower end portion 1111 than, for example, the upper end portion 1111 in the vertical cross-sectional view. When tilted so as to, the lower end portion 1110 will protrude most outward. Further, when the back surface portion 111 extends substantially vertically straight from the shoulder portion 12 toward the bottom portion 10 in the vertical cross-sectional view, the back portion 111 should protrude most outward in a part below the center in the vertical direction. Just do it.

The left and right side surface portions 112 and 113 are not particularly limited, but as shown in FIG. 9, in a vertical cross-sectional view from the front side, the left and right side surface portions 112 and 113 are curved outward from the shoulder portion 12 toward the bottom portion 10. The left and right side surface portions 112 and 113 are formed on a convex curved surface, while the left and right side surface portions 112 and 113 extend horizontally straight from the connecting portion 114 toward the connecting portion 115 in a cross-sectional view. Since the left and right side surface portions 112 and 113 have a small lateral width (length in the front-rear direction), a decrease in mechanical strength thereof is suppressed, and the structure is such that it is difficult to dent.

The shape of the connecting portions 114 and 115 is not particularly limited, and is formed to connect between the front portion 110 and the left and right side surface portions 112 and 113, and between the back surface portion 111 and the left and right side surface portions 112 and 113.

Explanation of the bottom The bottom 10 of the container 1 closes the lower end of the body 11 as shown in FIGS. 4 to 10. The bottom portion 10 is not particularly limited, but the central portion 100 is raised toward the accommodation space more than the outer peripheral edge portion 101. As a result, the container 1 can be stably placed on a horizontal table.

Description of Cover As shown in FIGS. 1 to 3, 12 and 13, the cover 5 includes a top surface portion 50 and a peripheral surface portion 51 hanging from the outer peripheral edge of the top surface portion 50. The cover 5 is not particularly limited, but is made of an elastically deformable synthetic resin material. When a container with a cover is used for the drug volatilizer, the cover 5 is provided on the container 1 in order to make it difficult to visually recognize the portion of the liquid absorbing core material 3 protruding from the container 1 from the viewpoint of the design of the drug volatilizer. It will be installed.

The peripheral surface portion 51 can fit the shoulder portion 12 of the container 1 inward, and the shoulder portion 12 is fitted into the peripheral surface portion 51. As shown in FIGS. 2 and 3, when the cover 5 is attached to the container 1, the lower end of the peripheral surface portion 51 abuts on the lower surface portion 122 of the shoulder portion 12 of the container 1. The peripheral surface portion 51 has no step between the peripheral surface portion 51 and the body portion 11 at the boundary with the body portion 11 of the container 1 (the lower end of the peripheral surface portion 51) over the entire circumference in the circumferential direction, that is, the bottom view of the lower end of the peripheral surface portion 51. The contour of the body and the contour of the upper end of the body portion 11 in a plan view are the same or almost the same, and the outer wall surfaces are connected to each other in a substantially flat manner.

The peripheral surface portion 51 does not necessarily have to have a step between the peripheral surface portion 51 and the body portion 11 over the entire circumference in the circumferential direction, and the peripheral surface portion 51 is slightly between the peripheral surface portion 51 and the body portion 11 at the boundary with the body portion 11 (lower end of the peripheral surface portion 51). The outer wall surface of the peripheral surface portion 51 may be located inside or outside the outer wall surface of the body portion 11.

At the lower end of the inner peripheral surface of the peripheral surface portion 51, a plurality of convex portions 52 protruding inward are provided at intervals in the circumferential direction. The plurality of convex portions 52 are preferably arranged at equal intervals, and in the present embodiment, the four convex portions 52 are arranged at intervals of 90 degrees. The protrusion 52 is engageable with the corresponding recess 125 of the shoulder 12 of the container 1. The convex portion 52 is not particularly limited, but exhibits an elongated shape (horizontally long shape) extending long in the circumferential direction.

As shown in FIGS. 12 to 14, the plurality of convex portions 52 are divided into a plurality of types having different vertical widths (lengths in the vertical direction). That is, at least the convex portion 52 having the largest vertical width and the convex portion 52 having the smallest vertical width exist. In the present disclosure, the convex portion 52 having the largest vertical width D1 is referred to as a first convex portion 52A, and the convex portion 52 having the smallest vertical width D2 is referred to as a second convex portion 52B. In the present embodiment, of the four convex portions 52, the convex portion 52 that enters the concave portion 125 (the first concave portion 125A having a large vertical width) located on the front side and the back side of the container 1 is the first convex portion 52A. The convex portion 52 that enters the concave portion 125 (second concave portion 125B having a small vertical width) located on the left and right side surface sides of the container 1 is the second convex portion 52B, which is the first convex portion than the vertical width D2 of the second convex portion 52B. The vertical width D1 of the portion 52A is larger. In the present embodiment, the plurality of convex portions 52 are of two types, a convex portion 52 having the largest vertical width (first convex portion 52A) and a convex portion 52 having the smallest vertical width (second convex portion 52B). However, there may be other protrusions 52 having different vertical widths in between.

Further, the plurality of convex portions 52 are provided separately at at least two different height positions in the vertical direction of the peripheral surface portion 51. That is, the plurality of convex portions 52 include a convex portion (convex portion provided at the highest height position) 52 at the position H1 where the height from the lower end of the peripheral surface portion 51 is the highest, and the lower end of the peripheral surface portion 51. There is at least a convex portion (convex portion provided at the lowest height position) 52 at the position H2 having the lowest height from the height. In the present embodiment, among the four convex portions 52, the height position H1 of the first convex portion 52A of the largest vertical width D1 is the highest, and the vertical width D2 of the second convex portion 52B of the smallest vertical width D2 is the largest. small,

As shown in FIGS. 16 and 17, when the cover 5 is brought close to the container 1 from directly above in order to mount the cover 5 on the container 1, the plurality of convex portions 52 of the cover 5 first have the smallest vertical width. The second convex portion 52B of D2 abuts on the shoulder portion 12 (overhanging portion 124 in this embodiment) of the container 1 and overcomes the shoulder portion 12 (FIG. 16A). After that, the first convex portion 52A having the largest vertical width D1 abuts on the shoulder portion 12 (overhanging portion 124 in this embodiment) of the container 1 and overcomes the shoulder portion 12 (FIG. 16B). Then, after the second convex portion 52B having the smallest vertical width D2 has entered the corresponding concave portion 125 (second concave portion 125B) of the container 1 (FIG. 17 (C)), the first convex portion 52A having the largest vertical width D1 is formed. Enters the corresponding recess 125 (first recess 125A) of the container 1 and finally engages with the recess 125 (first recess 125A) (FIG. 17D). As a result, the cover 5 attached to the container 1 can be fixed to the container 1 so that it cannot be easily removed from the container 1.

Further, when the cover 5 is pulled straight up from the container 1 in order to remove the cover 5 from the container 1, although not shown, the plurality of convex portions 52 of the cover 5 first have the first convex portion having the largest vertical width D1. The portion 52A exits from the corresponding recess 125 (first recess 125A) of the container 1, and then the second convex portion 52B having the smallest vertical width D2 exits from the corresponding recess 125 (second recess 125B) of the container 1. Eventually the engagement is disengaged. As a result, the cover 5 can be removed from the container 1.

Here, if the plurality of convex portions 52 provided on the cover 5 are all formed to have the same vertical width, when the cover 5 is attached to the container 1, all the convex portions 52 of the cover 5 are all formed on the container 1. Since it is necessary to insert the cover 5 into the recesses 125 all at once and engage them, it is difficult to attach the cover 5 to the container 1. Further, when the cover 5 is removed from the container 1, all the convex portions 52 of the cover 5 need to be pulled out from all the concave portions 125 of the container 1 all at once to disengage the engagement. Therefore, the cover 5 needs to be disengaged from the container 1. Difficult to remove from.

On the other hand, in the present embodiment, the plurality of convex portions 52 are divided into a plurality of types having different vertical widths, and are provided on the cover 5 when the cover 5 is attached to the container 1. All the convex portions 52 are inserted into all the concave portions 125 of the container 1 at the same time and are not engaged with each other. First, the corresponding concave portion 125 (second convex portion 52B) having the smallest vertical width D2 is used as a guide. After entering the second concave portion 125B), the convex portion 52 (first convex portion 52A) having the largest vertical width D1 is inserted into the corresponding concave portion 125 (first concave portion 125A) and finally engaged. The cover 5 can be easily attached to the container 1. Further, even when the cover 5 is removed from the container 1, all the convex portions 52 of the cover 5 are simultaneously pulled out from all the concave portions 125 of the container 1 to prevent the engagement from being disengaged, and the convex portions 52 having the largest vertical width D1. (First convex portion 52A) is first pulled out from the corresponding concave portion 125 (first concave portion 125A), and then the convex portion 52 (second convex portion 52B) having the smallest vertical width D2 is made to correspond to the corresponding concave portion 125 (first convex portion 52B). Since the cover 5 is finally disengaged from the two recesses 125B), the cover 5 can be easily removed from the container 1.

In addition, in the present embodiment, the first convex portion 52A to be finally engaged has a large vertical width, and is strongly engaged with the corresponding concave portion 125 (first concave portion 125A) to be strongly engaged with the concave portion 125 (first concave portion 125A). It is difficult to get out of. Therefore, when the cover 5 is attached to the container 1, the cover 5 can be firmly fixed to the container 1, and for example, when the cover 5 is gripped and the container 1 is lifted, the container 1 is prevented from falling off from the cover 5. can do.

As described above, the cover 5 is fixed to the container 1 by the first convex portion 52A having the largest vertical width D1 entering and engaging with the corresponding first concave portion 125A. Therefore, it is preferable that the cover 5 includes a plurality of first convex portions 52A having the largest vertical width D1, and it is more preferable that the plurality of first convex portions 52A are arranged at equal intervals. In this embodiment, a pair of first convex portions 52A are arranged to face each other (every 180 degrees).

Further, as shown in FIG. 12, the first convex portion 52A preferably has a central portion 520 in the lateral width direction protruding more inward than both end portions. Since the central portion 520 of the first convex portion 52A has a long protrusion length from the inner wall surface of the peripheral surface portion 51 of the cover 5, when the cover 5 is attached to the container 1, the first convex portion 52A is formed. In this central portion, it penetrates deeply into the corresponding recess 125 (first recess 125A) of the container 1 and strongly engages with the recess 125 (first recess 125A). Therefore, the cover 5 can be firmly fixed to the container 1. The first convex portion 52A does not necessarily have to have the central portion 520 in the lateral width direction protruding more inward than both end portions.

The cover 5 can be easily attached to the container 1 by the second convex portion 52 having the smallest vertical width D2 functioning as a guide. Therefore, it is preferable that the cover 5 includes a plurality of second convex portions 52B having the smallest vertical width D2, and it is more preferable that the plurality of second convex portions 52B are arranged at equal intervals. As a result, the cover 5 can be attached to the container 1 without rattling. In this embodiment, the pair of second convex portions 52B are arranged to face each other (every 180 degrees). The vertical widths of the plurality of concave portions 125 of the container 1 are set according to the height position and vertical width of the corresponding convex portions 52 of the cover 5 that enter each of them as described above.

Further, as shown in FIGS. 13 and 15, the second convex portion 52B is preferably provided with a notch 521 in the central portion in the lateral width direction, and is divided into two left and right portions. Since the second convex portion 52B is divided into two left and right portions, the second concave portion 52B of the cover 5 smoothly becomes the container 1 when the cover 5 is attached to the container 1 and when the cover 5 is removed from the container 1. It goes into the corresponding recess 125 (second recess 125B) and exits from the corresponding recess 125 (second recess 125B). Therefore, it is possible to easily attach / detach the cover 5 to / from the container 1. The second convex portion 52B does not necessarily have to be provided with a notch portion 521 at the central portion in the lateral width direction.

A plurality of holes 53 are formed in the top surface portion 50 and the peripheral surface portion 51 of the cover 5. The hole 53 functions as a volatilization hole for discharging the drug component of the liquid drug that is sucked up and volatilized by the liquid absorbing core material 3 to the external space when the container with a cover is used for the drug volatilizer.

Description of Exterior Film As shown in FIG. 18, the exterior film 6 covers the container 1 (among them, the body portion 11) and the cover 5 of the container with a cover. The exterior film 6 is not particularly limited, but a film (shrink film) that is arranged in a cylindrical shape so as to surround the container 1 and the cover 5 and that wraps around the container 1 and the cover 5 by shrinking due to heating can be used. The exterior film 6 is decorated with a product name, a product description, a pattern, etc., and the area corresponding to the front portion 110 of the container 1 is particularly for advertising / promotion of the product name, product appeal design, etc. Displayed and decorated.

On the exterior film 6, an easily dividing line 62 such as a perforation is formed between the portions 60 and 61 so that the portion 60 covering the cover 5 and the portion 61 covering the body portion 11 of the container 1 can be easily separated. It is provided all around in the direction. As a result, the user can remove the cover 5 from the container 1 while keeping the container 1 covered with the exterior film 6 by separating only the portion 60 covering the cover 5 of the exterior film 6 and peeling it from the cover 5. The easily dividing line 62 of the exterior film 6 is provided on the exterior film 6 so as to be close to the boundary (the lower end of the peripheral surface portion 51) between the body portion 11 of the container 1 and the peripheral surface portion 51 of the cover 5. The position of the easily dividing line 62 of the exterior film 6 does not have to completely coincide with the boundary (lower end of the peripheral surface portion 51), and may be slightly displaced in the vertical direction (for example, about 10 mm). Further, the portion 60 covering the cover 5 of the exterior film 6 is provided with an easily dividing line 63 such as a perforation perpendicular to the easily dividing line 62.

Action / effect of container with cover

According to the container with a cover of the present embodiment described above, the plurality of convex portions 52 of the cover 5 are divided into a plurality of types having different vertical widths. Therefore, when the cover 5 is attached to the container 1, all the convex portions 52 provided on the cover 5 are not engaged with all the concave portions 125 of the container 1 at the same time, and the convex portions having a small vertical width are not engaged. The convex portion 52 and the concave portion 125 are engaged with each other by inserting the convex portion 52 having the largest vertical width into the corresponding concave portion 125 of the container in order from 52 as a guide. Therefore, it is possible to easily attach the cover 5 to the container 1. Further, when the cover 5 is removed from the container 1, all the convex portions 52 of the cover 5 are simultaneously pulled out from all the concave portions 125 of the container 1 to prevent the engagement from being disengaged, and the convex portions 52 having the largest vertical width are sequentially removed. By pulling out of the corresponding concave portion 125 of the container 1 and finally pulling out the convex portion 52 having the smallest vertical width from the corresponding concave portion 125 of the container 1, the engagement between the convex portion 52 and the concave portion 125 is released. , The cover 5 can be removed from the container 1.

Further, according to the container with a cover of the present embodiment, the convex portion 52 having the largest vertical width to be finally engaged has a large vertical width, and is strongly engaged with the corresponding concave portion 125 of the container 1 and escapes from the concave portion 125. It's getting harder. Therefore, when the cover 5 is attached to the container 1, the cover 5 can be firmly fixed to the container 1.

Further, according to the container with a cover of the present embodiment, the lower end portion 1110 of the container 1 on the back surface portion 111 of the body portion 11 protrudes most outward in the vertical cross-sectional view. As a result, as shown in FIG. 19, when the other containers 1 are arranged directly opposite the back surface portion 111, the lower end portion 1110 of the back surface portion 111 abuts on the other container 1 while the upper end portion 1111 Does not abut on the other container 1, and the boundary B between the body portion 11 and the cover 5 (the lower end of the cover 5) creates a gap S between the body 11 and the cover 5 and the other resin container 1.

Here, it is common that a plurality of containers with covers are transported side by side in a cardboard box in a state of being wrapped by the exterior film 6, or a plurality of containers are displayed side by side at a store. At this time, as shown in FIG. 20, a part of two adjacent containers 1'may come into contact with each other, but the boundary B between the container 1'and the cover 5'(the lower end of the cover 5') is adjacent to the container. When it comes into contact with 1', the easily dividing wire 62' of the exterior film 6'is damaged by the contact. In particular, if the easily dividing line 62'of the exterior film 6'is at the boundary B between the container 1'and the cover 5'(the lower end of the cover 5'), the easily dividing line 62'of the exterior film 6'is damaged. It is easily damaged, and the exterior film 6'may be unintentionally broken. On the other hand, in the container with a cover of the present embodiment, since the container 1 comes into contact with the adjacent container 1 at the lower end portion 1110 of the body portion 11, the easily dividing line 62 of the exterior film 6 connects the container 1 and the cover 5. Even if the container is close to the boundary B (lower end of the cover 5), the container 1 adjacent to the easily dividing line 62 of the exterior film 6 does not come into contact with the easily dividing line 62 during transportation or exhibition of the container with the cover, so that the easily dividing line 62 is formed. It is possible to prevent the exterior film 6 from being damaged and broken.

Further, according to the container with a cover of the present embodiment, since the lower end portion 1110 of the back surface portion 111 of the body portion 11 of the container 1 protrudes to the outermost side, the exterior is made by arranging the other containers 1 directly opposite the back surface portion 111. Since the easily dividing wire 62 of the film 6 can be prevented from being damaged, the containers with covers can be efficiently arranged. In addition, the protruding lower end portion 1110 can be prevented from being noticed by the purchaser during the display of the container with a cover, and the deterioration of the design of the container with a cover can be suppressed.

Further, according to the container with a cover of the present embodiment, the back surface portion 111 of the body portion 11 of the container 1 is curved inwardly in a concave shape in a vertical cross-sectional view. As a result, even if the lower end portion 1110 of the back surface portion 111 protrudes to the outermost side, the design of the container with the cover is not adversely affected.

Modifications of a Container with a Cover Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

In the above-described embodiment, the plurality of convex portions 52 provided on the cover 5 are composed of a plurality of types of convex portions 52 having different height positions, but the convex portions 52 are all arranged at the same height position. You may. In this modification, for example, as shown in FIG. 21, among the four convex portions 52 of the above-described embodiment, the first convex portion 52A having the largest vertical width D1 is also the second convex portion 52B having the smallest vertical width D2. It is at the same height position as (the height from the lower end of the peripheral surface portion 51 of the cover 5 is the position of H2).

In this modification, as shown in FIG. 22, when the cover 5 is brought close to the container 1 from directly above in order to mount the cover 5 on the container 1, the plurality of convex portions 52 of the cover 5 have the largest vertical length. The first convex portion 52A having a width D1 and the second convex portion 52B having the smallest vertical width D2 both abut against the shoulder portion 12 (overhanging portion 124 in the illustrated example) of the container 1 and overcome it (FIG. 22 (A)). .. Then, after the second convex portion 52B having the smallest vertical width D2 has entered the corresponding concave portion 125 of the container 1 (FIG. 22 (B)), the first convex portion 52A having the largest vertical width D1 corresponds to the container 1. It enters the recess 125 and finally engages with the recess 125 (FIG. 22C). As a result, the cover 5 attached to the container 1 can be fixed to the container 1 so that it cannot be easily removed from the container 1.

On the other hand, when the cover 5 is pulled straight up from the container 1 in order to remove the cover 5 from the container 1, although not shown, the plurality of convex portions 52 of the cover 5 first have the first convex portion having the largest vertical width D1. The portion 52A exits the corresponding recess 125 of the container 1, and then the second convex portion 52B having the smallest vertical width D2 exits the corresponding recess 125 of the container 1 and is finally disengaged. As a result, the cover 5 can be removed from the container 1.

Therefore, also in this modification, as in the above-described embodiment, first, the convex portion 52 (second convex portion 52B) having the smallest vertical width D2 is inserted into the corresponding concave portion 125 as a guide, and then the largest vertical portion is formed. Since the convex portion 52 (first convex portion 52A) having the width D1 is inserted into the corresponding concave portion 125 and finally engaged, the cover 5 can be easily attached to the container 1. Further, when the cover 5 is removed from the container 1, the convex portion 52 (first convex portion 52A) having the largest vertical width D1 is first pulled out from the corresponding concave portion 125, and then the convex portion having the smallest vertical width D2. Since the 52 (second convex portion 52B) is pulled out of the corresponding recess 125 and finally disengaged, the cover 5 can be removed from the container 1.

In the modified example shown in FIG. 21, the first convex portion 52A having the largest vertical width D1 and the second convex portion 52B having the smallest vertical width D2 have the same height H2 from the lower end of the peripheral surface portion 51 of the cover 5. Because it is, it is in the same height position. However, as shown in FIG. 23, the height H2 of the lower end of the second convex portion 52B having the smallest vertical width D2 is higher than the height H3 of the lower end of the first convex portion 52A having the largest vertical width D1. Moreover, the height H2 + D2 at the upper end thereof is lower than the height H3 + D1 at the upper end of the first convex portion 52A having the largest vertical width D1, so that the height may be the same.

In this modification, as shown in FIGS. 24 and 25, when the cover 5 is brought close to the container 1 from directly above in order to mount the cover 5 on the container 1, the plurality of convex portions 52 of the cover 5 are formed. First, the first convex portion 52A having the largest vertical width D1 abuts on the shoulder portion 12 (overhanging portion 124 in the illustrated example) of the container 1 and overcomes the shoulder portion 12 (FIG. 24 (A)). After that, the second convex portion 52B having the smallest vertical width D2 abuts on the shoulder portion 12 (overhanging portion 124 in the illustrated example) of the container 1 and overcomes the shoulder portion 12 (FIG. 24 (B)). Then, after the second convex portion 52B having the smallest vertical width D2 has entered the corresponding concave portion 125 of the container 1 (FIG. 25 (C)), the first convex portion 52A having the largest vertical width D1 corresponds to the container 1. It enters the recess 125 and finally engages with the recess 125 (FIG. 25D). As a result, the cover 5 attached to the container 1 can be fixed to the container 1 so that it cannot be easily removed from the container 1.

On the other hand, when the cover 5 is pulled straight up from the container 1 in order to remove the cover 5 from the container 1, although not shown, the plurality of convex portions 52 of the cover 5 first have the first convex portion having the largest vertical width D1. The portion 52A exits the corresponding recess 125 of the container 1, and then the second convex portion 52B having the smallest vertical width D2 exits the corresponding recess 125 of the container 1 and is finally disengaged. As a result, the cover 5 can be removed from the container 1.

Therefore, also in this modification, as in the above-described embodiment, first, the convex portion 52 (second convex portion 52B) having the smallest vertical width D2 is inserted into the corresponding concave portion 125 as a guide, and then the largest vertical portion is formed. Since the convex portion 52 (first convex portion 52A) having the width D1 is inserted into the corresponding concave portion 125 and finally engaged, the cover 5 can be easily attached to the container 1.
